The National Nuclear Security Administration is proposing new construction activities in lower Sandia Canyon at Technical Area 72 at the Outdoor Live Fire Range facility within Los Alamos National Laboratory.

The proposed improvements to the facility, which is located off East Jemez Road not far from the intersection with Hwy 4, include construction and use of a new warehouse, a new sanitary holding tank, range upgrades, a new dual-purpose shooting range with access roads, and streambed channel corrective actions within the 100-year floodplain.

The purpose of the proposed construction is to provide improved and expanded training facilities for LANL security services, reduce potential damage to facilities from flood events, and mitigate streambed channel erosion.

NNSA has prepared the required floodplain assessment for the proposed project. It evaluates potential impacts to floodplain values and functions from the project, identifies alternatives to the proposed action and allows for meaningful public comment.

The Floodplain Assessment is available in the LANL Electronic Public Reading Room, on the DOE NEPA Documents webpage https://www.energy.gov/sites/prod/files/2018/11/f57/TA-72FloodplainAssessment.pdf, or in hard copy at the LANL Public Reading Room, 94 Cities of Gold Road, Pojoaque, NM.

The 15-day public comment period ends November 20, 2018. To submit comments or for further information contact Kristen Dors of the NNSA Los Alamos Field Office Office  at Kristen.Dors@nnsa.doe.gov.
